Dear group, Meanwhile I tried also attached example, which is basically spawning threads in threads. This gives absolutely no problem, giving me some minimum confidence pthreads is OK on my machine. On the other hand ... if pthreads works, it looks to me the issue must be somewhere in the libgomp which works however on Linux (gcc 4.4.1 in Ubuntu) ... Can anyone give me some hints as where to start finding this issue ?
